Definitions

  • This invention relates to an electric appliance for personal use such as a dry shaving apparatus, a hair cutting machine or epilator, having a housing to accommodate an electric motor, a storage cell charging circuitry, at least one rechargeable storage cell designed to be connected to the electric motor, and a connector compartment in which a connector equipped with connector pins is pivotally mounted.
  • the connector comprises a connector housing and two leaf-shaped connector pins projecting from the connector housing.
  • German utility model G 83 29 691 U1
  • the connector of a rechargeable shaving apparatus is slidably positioned at one end of the shaver housing so that the two leaf-shaped connector pins fastened to a connector housing are pushed out of one of the two narrow sides of the shaver's housing by means of an actuator switch arranged in the bottom of the housing in order to make the connection to a socket-outlet of a voltage source.
  • an actuator switch arranged in the bottom of the housing in order to make the connection to a socket-outlet of a voltage source.
  • Electric appliances of the type initially referred to are known to be equipped with various connectors in conformance with various standards, e.g. connectors with relatively close lying leaf-shaped connector pins for 110 volts/125 volts or round connector pins for 220 volts, 230 volts/240 volts, which compared with the leaf-shaped connector pins are spaced further apart because of the higher voltage involved.
  • the spacing to be observed for round connector pins to conform with applicable standards makes it impossible to replace leaf-shaped connector pins with round connector pins, for example, on the known arrangement of the connector arranged to be pivoted out of a broad side of the shaver's housing according to FIG. 18 of Japanese patent publication 60-39390 (B2) on account of the relatively slim shaver housing.
  • this object is accomplished by the combination of features specified in claim 1 .
  • the connector pins are held inside the connector housing in a locking position in order, for example, to prevent rattling noises while transporting the electric appliance or obstructions by the connector pins while pivoting the connector housing in and out of the connector compartment.
  • the connector pins are adapted to be acted upon by at least one spring.
  • the spring is arranged between a rear wall of the connector housing and a connector pin pusher fixedly connected to the connector pins.
  • the connector housing is equipped with at least one locking element, and for each locking element there are provided two latching elements on the housing in order to limit the pivoting movement of the connector out of and into the housing.
  • the connector is preferably pivotally mounted in the connector compartment by means of two bearing pins.
  • the pivot bearing for the bearing pins is formed by corresponding semi-circular recesses in a first and a second shell of the housing.
  • each of the two bearing pins prefferably be positioned a certain distance from each end wall of the connector.
  • each connector pin prefferably connectable to an electric contact of the storage cell charging circuitry via an electric contact while the connector is pivoted out of the connector compartment.
  • the connector pins prefferably be of a round configuration.
  • the connector pins Owing to the fact that the distance between leaf-shaped connector pins is substantially smaller than the distance between round connector pins, provision is made in accordance with an alternative embodiment of the invention for the connector pins to be of a leaf-shaped configuration.
  • Handling the connector of the present invention is greatly simplified in accordance with a preferred embodiment in that the actuating element is movable in one locking position against an unlocking element provided in the housing.
  • the connector pins are capable of being unlocked by means of the unlocking element acting on the actuating element when the connector housing is pivoted into the interior of the connector compartment.
  • the connector pins are preferably held by the spring in abutting engagement with a wall of the connector compartment.
  • a significant advantage of this embodiment is that the unlocked connector pins are moved by the spring automatically out of the connector housing into a locking position when the connector is pivoted into its operating position.
  • the unlocking element is positioned on a wall of the housing.
  • yet further embodiments of the invention provide for the unlocking element to be positioned on a printed-circuit board in the housing.
  • unlocking the actuating element is facilitated by configuring the unlocking element as a protruding, rounded ledge.
